I love music.want to set it as my career.but I know its not allowed in Islam.So what should I do if I don't do what I love then I suppose there is no chance to be successful

What would you want to do in music?

So, you do not do music. If you believe in your religious faith, you must follow it.
I would assume you like music but would not have any experience in working in music. So you really do not know if you like that type of work or not.

You chose another job doing something you also can enjoy if possible.
